It’s called regularly cleaning. Specifically in this case; dusting.

They sell cheap dusting tools, some exclusively for reaching tall places that are difficult to routinely clean. They’re called extendable dusters/dust wands. You can buy them at any general store.

Dust accumulates quickly on tall furniture due to air circulation which carry dust particles upwards. Especially in rooms that use HVAC systems, fan or natural drafts. Then, gravity kicks in, causing the dust particles to settle on any available surfaces with the inclination of the highest possible surfaces, in corners and edges of the room due to its height and location.

Additionally various furniture materials will trap dust particles more easily due to static electricity and the interaction with the material (like wood). The texture of the materials also play a role, as rough surfaces trap dust particles more easily than smooth surfaces.

There are also environmental factors, from inside homes with a lot of carpets, textile furniture, long curtains, pets tend to build up way more dust than without. Fabrics like velvet, wool, fleece, acrylic, fiber blends that mix synthetic and natural fibers attract and generate a lot of clothing fibers that contribute quite a bit to dust accumulation.

As for, outside environmental factors, people that live in large cities, nearby industrial zones, dry places, etc. there's going to be a lot of particulate matter; air pollution, dust, soot, smoke, aerosols, sand. Especially where climate is arid compared to humid climate.

To reduce dust accumulation,
- you'd need to vacuum more frequently using a quality vacuum with a HEPA filter and empty it regularly (which albeit is rather wasteful when using disposable bags)
- use microfiber cloth more often on the surfaces you can easily reach
- rethink your choice of fabrics indoors, avoid carpets - opt for natural fibers
- if you have pets groom them outside daily or invest in a pet grooming vacuum.
- invest in a humidifier, some plants and anti-static products
- when using fans avoid using them in areas where dust accumulates the most, place them up high and create cross-ventilation.
- consider replacing those closets/cabinets/bookcases with ones that reach from the floor to the ceiling or close the space somehow by building small cabinets or storage areas for you.

Get a Roomba.

Pile it up with every box you can find.

So my main issue is my closet. It's built off the wall and creates a shelf on the top of it next to my ceiling fan and wall register. Dust for some reason like to accumulate on top of my closet, and the top of the closet is 8 ft high so its not easy to clean without a ladder. This tends to cause more dust to accumulate in my whole room no matter how much i dust and vacuum. Is there anything I can do to help decrease the dust accumulation?

I have the same problem. My computer is in the lowest level of a 3 1/2 level home and ALL the dust works its way down to the bottom. Darn you Gravity!

If I were to build another PC I would probably do liquid cooling.

You can buy a air purifier and regularly replace the filters and clean it. It won't get everything, but it will help.

I do clean regularly, its just more so the top of the closet is next to a wall register and my ceiling fan. It doesn't help my ceiling is sloped as well.

You could try a HEPA filter in the room.

The hepa filter idea isn't bad. But when it comes to redoing the closet that's easier said then done, my room is on the remodeled part of our house and I can't just change things I still live at home with my parent. I also cant change where my ceiling fan is as its hardwired into a sloped ceiling so it makes things difficult.

I have been thinking about getting a purifier

If it is not due to air conditioning, you should check to see if your windows and door to that room is properly sealed, that way you can eliminate outside dust.

That said, over half of "dust" is usually human dead skin, so if its just you in a small room, find a good loofah/pumice stone and scrub off your dead skin in the shower, like once a week or what ever works for you, add in some moisturizer to for your skin care routine so you keep your skin longer, especially if you are in an excessively dry place.

If you wanted to try other out of the box things.

invent a shrink ray and shrink yourself down to the size of the dust and begin a campaign against it on its turf!

ESD ioniser

One more factor is ceiling fans are great. I run mine endlessly.

But they need at least a quarterly cleaning- or they will accumulate dust.
